DAR-IE8 ORION GREEN, OF BICKNELL, INDIANA.

CAR ROOF.

Application filed January 17,1919 Serial No. 271,575.

To all whom itmiz-g concern.

Be it known that IYDARIES ORION GREEN,

a citizen of the United States of America,-

acter especially designed and adapted for.

use in connection with railway cars and of the type generally known as outside metal roofs, and an object of the invention is to provide a novel and improved roof wherein the attachmentof the parts to the substructure will not cause the same to be split or broken by the vibrations or deflections there- It is also an object of the invention to provide a novel and improved roof of this general character wherein the various parts comprised therein can be produced by machine from sheet metal and whereby said parts can be readily repaired and straightened or restored to the proper form with tools ordinarily used in general car repairing.

Another object of the invention is to provide a. novel and improved roof which includes parts which may be readily adjusted to the varioussizes of cars so that cutting and fitting of the parts will not be necessary in applying the same.

A still further object of the invention is to provide a novel and improved roof wherein metal of any desired thickness can be employed in making the several parts.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved car roof whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the ac companying drawings, wherein:

.Figure 14 is a perspective View of an end view of a main sheet with a portion broken away to show the wide underturned flange; and

Fi ure 15 is a perspective view of an end flashing sheetf Asdisclosed in the accompanying drawings, my improved roof comprises the main sheets l disp0sed transversely of the roof decking 16 and extending in opposite directions from the ridge pole 15. The upper end portion of each of the sheets 1 is return bent to form a wide overturned flange, as-

illustrated at 28 in Figures 4, 6 and 9 to interlock with the underturned flange 59 of the seam cap 7 and thus provide a means for expanding or contracting the roof for various widths of cars.

As is particularly illustrated in Figure 9, each of the main sheets 1 is producef from a blank sheet of material having tlie cor ners at the upper or inner end cut away at right an and the opposite corners cut away on course angles. The side portions 2 of the sheet turned up at right angles to the plane of the sheet with one end of side portions ranged at angles to the sheet pronei and the opposite ends sloping down to the plane of the sheet The unper or i end portion of sheet 1 is turned over inpara-llelisrn vith the plane of the sheet. as indicated at 28 in Figures l 6 and forming a wide flange enacting wi wide of the ridge seam cap. opposite end portion of the sheet 1. is irncn down forming a depending l whi covers portion of the fascia board 11.

portion 22 of the sheet 1 c with a rebentflange 23,, Figure is into a groove 2% disposed longii of the fascia board ll, Eigures and 10. The fringe 23 is f angles to tie depending portion of the sheet 1 with the rehent portion of the flange de pending downward and outward at an angle of do degrees and terminating'on aline parallel with the inner plane of the depending end of the sheet. When applied to a car, flange 23 is held in the grow/e24 by guards 10, Figure 11, also Figures 3, i and 5. B37 means of the fascia board ll and guards the sheets 1 are loosely held in place.

l t hen applied to the decking 16, the up standing side port-ions or flanges 21 are closely related, and disposed over each pair of adjacent portions or flanges 21 is a subseani cap 5. The subseain cap 5, Fi 5., shown in perspective in Figure 8, is formedfrom aplane sheet of metal bent to a lJ-shape in cross section with the free marginal portions 25 of the sides turned out approximately 60 degrees forming flanges. The purpose of the flanges 25 are to be compressed on the surface of the main sheets 1 to malte a flexible, dust-proof and waterproof joint.

After the suloseain cap 5 has been applied the scam cap 4 is fitted thereover, as illus t-rated in Figures 4 and 5. The seam cap t is formed from sheet metal, preferably heavier than the sheets 1 and the subsearn. cap 5. The major portion of the cap lis substantially U-shaped incross section and the side flanges thereof snugly engage the sides of the subseain cap 5 above the portions 25 thereof.

The outer end of the cap 4, Figs. 6 and 7,, is continued by a depending end plate 26 and has its outer end portion bolted to the fascia board 11 and to the side plate The depending end or plate 26 covers the joint between the adjacent sheets 1 and its upper portion is outwardly offset as at 27,

Figs. 6 and 7 so that when said end or lb iornied at right 2 to form an expansion joint.

plate 20 is bolted to the fascia hoard, the sets 1 ner cut away on. an obtuse angle. A longitudinal marginal portion is turned up at' right angles to the sheet to all'ord a flange 29 with one end at right angles to the sheet and the opposite end sloping'to the plane ofthe sheet corresponding to the flange 21 of a sheet 1.

The opposite longitudinal marginal. portion of the blank for the end sheet 2 is turned under to produce a [hinge 30 parallel with the plane of the sheet. One end of the hlanlr is turned over to parallel with the plane of the sheet to produce the wide llange 31 which when assembled engages with the wide flange 32 of the end ridge cap The opposite end of the blank is turned down to form a depending end or plate 39 which covers a portion of the fascia board 11 to make a flashing. The depending end or flashing 39 has a rehent flange 38 turned inwardly and under the sheetat right angles with the plane of the flashing thence lownward and outward at about degrees terininatingon a line parallel with the inner plane ofthe flashing o conform with the flange 223, sheet 1.

An end sheet 2 is laid at each corner with the flange 30 engaging the flange 33 of an end flashing sheet The end flashing sheet- 3 is particularly illustrated in Figure 15 and is shown assembled in Figures 2, 3. t and 5. As can be seen by Figure 15. the end flashing sheet is formed from a rectangular blank sheet of material hating the four'corners cut away at right angles. A

longitudinal marginal portion of the hlank is turned overparallel with the plane of the sheet to produce the flange which interlocks with the flange 30 of an end sheet The expansion joint provides a means by which the roof can he adjusted to different length of cars. By referring to Figure 5 it can be seen that the end flashing sheet 3 can be located anywhere between the points cf. Taking one foot as the distance between the points e-f there is a range of'ono foot plus one foot at the opposite end of the roof making a total of two feet, the longitudinal range of adjustment of the roof. Thereby the roof can be applied to a car thirty feet long or a car thirtytw feet long or a car of any length between thirty and thirtytwo feet.

ill)

The opposite longitudinal marginal portion of the blank for sheet 3 is turned down forming a depending side or plate 31 which covers a portion of the fascia board ll-and forms a flashing. The plate 34 has a rebent flange 35 to conform to the rebent flange 23 of sheet 1. The outer end portion of the blank for sheet 3 is also turned down to form a flashing 36 which has a rebent flange 37 which conforms with the rebent flange 23 of sheet 1. The inner or upper end portion of the blank for sheet 3 is left flat and when assembled extends up and under the 'end ridge seam cap 8.

Co-acting with the flanges 23, 35, 37 and 38 of sheets 1, 2 and 3, are the guards 10 which hold the sheets loosely in their relative position to the substructure.

Coacting with the ridge ends of the sheets 2 and 3 isthe end ridge seam cap 8 and which end ridge seam cap is of substantially the same construction as the main ridge seam cap 7 illustrated in Figure 13 with the exception that one end of the end ridge cap 3 is divided at substantially its transverse center, the divided portions being turned down forming plates 10 and 41. Figure 12, which overlie a portion of the fascia board 11 and are bolted or otherwise fastened thereto. The end ridge cap also has wide underturned flanges 32 which intersect with the wide overturned flanges 31 of the end sheet 2 to form an expansion joint. The opposite end of the end ridge cap 8 has a chan nel 42, formed to coact with a channel 43 of a ridge cap 7.

The main ridge seam cap 7 as is illustrated in Figure 13, is formed from a rectangular sheet of material having the fourcorners cut away at right angles. and the longitudinal side portions fol ed under to parallel with the place of the sheet to form the wide flanges 59. which co-act with the wide flanges 28 of a main sheet 1 to produce an expansion joint as shown at 59 and 28, Figure 4. The distance between the' points 71, Figure at, is assumed to be six inches. Therefore the sheet 1 can be moved outwardly a distance of six inches and the sheet 1 directly opposed on the opposite side of the car likewise can bemoved outward a distance of six inches making a total of twelve inches or one foot as the range of adjustment that the roof can be transversely adjusted. By means of the expansion joints thus provided the roof can be applied to a car eight feet wide or a car nine feet wide or a car of any width between eight and nine feet.

The marginal end portions of the main ridge seam cap 7 are each formed into a channel shape as shown at 13 and 44, Figure 13. The channel at one end of the cap is larger than the channel at the opposite end and when assembled the larger channel of a seam cap fits over the smaller channel of the adjoining seam cap. The seam caps are held in place by a runningboard saddle bolt 20 which is placed through the openings 15, Figures 12 and 13, and shown assembled \in Figure 6. seam cap 7 and the end ridge seam capS are each bent longitudinally on the line 46 to conform to the pitch of the roof.

The end portions of the sheets 1, 2 and 3 overlying the fascia board 11 are held in their respective positions by guards 10. The guards 10 shown in Figure 11, and assembled in Figures 3, 1 and 5, are formed from a flat sheet of material having one marginal edge bent to right angles to the sheet forming a flange 47. The guard is provided with an opening 18 for the passing of the bolt 419, Figure 5, and openings 50 are provided for-the passage of nails. or other like meansof fastening. W'hen assembled, the guard 10 is secured to the fascia board 11 by means of the bolt 49, Figure 5,

with the flange 17 engaged within the rebent flange of the flashing plate whereby the guard 10, together with the fascia board 11 hold the sheets in their proper position to the substructure without clamping them to the fascia board.- This is made possible by the peculiar shape of the groove 21 in the fascia board 11 and the flange 35.

Co-act-ingwith each corner of the roof is the corner cap 9, Figure 4. The cap 9 is formed from a rectangular blank sheet of material having one corner cut away on a diagonal line near to the next adjacent marginal corners. The diagonally opposed corner is cut away at right angles. The two remaining marginal portions of the sheets are then turned down to approximately right angles to the plane of the sheet forming a three sided cup or cap. The two depending sides of thecap overlie a por tion of thefascia board 11 and are provided with openings for passing of bolts by which they are secured to the fascia board. It can be seen that the free depending sides of the cap 9 make it adjustable to the pitch of the roof. I

CO-acting with the flange 33 of the end flashing sheet 3, Figures 5 and 15, are the clips 51 preferably made of a heavier material than the sheet 3. The clips 51 are made secure to the flange and reinforce it against the action of the flange 30 of sheet 2;

The saddles 18 are of a well known type and support the running boards 19. As hereinbefore stated, each of the saddles 18 is secured'to the ridge pole '15 by the bolts 20. Each of the bolts 20 has its head seated ing. 52 which may be of any suitable type.

The saddle 18 is grooved on the under face The 1 main ridge within a recess or pocket in the upperface seam cap 5.

to fit over the channels 43 of the seam cap 7 and the ends of the seam cap l.

The saddle support 53, Figure 6, pro ides a means of supporting a running board saddle to prevent the saddle clamping the root sheet 1 when said saddle is drawn down by the bolt 20. T his means comprises a saddle support preferably of cast iron made to 1 contorm LO the pitch of the root wi n tne sides thereof concave in cross section and provided at substantially its center with an opening for the passage of the bolt 20. l'he support 53 is placed over the decking 16 and ridge pole 15 and under the seam cap Y.

Co-acting with the seam cap l, Figure 5, is the sleeve 54. The sleeve 5% is preferably cylindrical in shape and having a flange on one end to prevent it being imbedded into the decking 16. It is of the proper length to extend from the decking to the underside of the seamcap 4, and is provided with an opening through the center for passing the bolt 55. The subseam cap 5 has an openin; 56, Figure 8, which is large enough to allow the sleeve 5a to pass through and allow free movement of the subseam cap. The seam cap t has an opening 5?, Figure 7, which opening has an upstanding flange 58 against which the head of the bolt 55 is seated. The sleeve 54 is placed on the decking'lti between the flanges 29 of the root sheets and the subseam cap 5 is placed over the sleeve and flanges of the roof sheets. The seam cap at is placed over the subseam cap 5 and the bolt 55 inserted through the opening provided therefor drawing the seam cap 4 down on the flanges 25 of the sub- The sleeve 54 receives the ten sion of the bolt between the decking l6 and the seam cap a and holds the seam cap rigidly in place without clamping the root sheets 1 and 2 to the decking 16 so that the said sheets are free to adjust themselves to the different positions caused by the vibrations of the roof structure. The subseamcap 5 is also free of any rigid fastening and is always in contact with the roof sheets either by tension of the seam cap 4 on the flanges 25 or by gravity.

From the foregoing description, it is thought to be obvious that a car root con structed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles andspirit thereof and for this reason I do not wish to be understood as limiting. myself to the-precise arrangement and formation of the several parts herein. shown in carrying out my invention in practice except as hereinafter claimed.

It will also be obvious from the foregoing description that allot the parts comprised in my improved root can be made or formed by stamping or pressing metal sheets'of any thickness desired in specially designed dies and machines and that my improved root can be secured to the substructure in a way that will permit of deflection and vibration without buckling or straining tne roof sheets. it is also to be noted that t re sea-m. caps are bolted to the substructure in a manner to retain the root" or main sheets in their proper alinement and compressing the flexible .subseam cap of the main sheets 3'. to provide constant waterand dud-proof joints.
